Methods for Receiving and Transmitting Single-Cell Multicast Service, User Equipment, and Base Station

1. A method performed at user equipment (UE), comprising: in a case that (a) a common search space for a first narrowband physical downlink control channel (NPDCCH) scrambled by a Radio Network Temporary Identity (RNTI) corresponding to a Single-Cell Multicast Control Channel (SC-MCCH) is assigned within a first subframe which is configured by a system information block and (b) the first subframe is a specific subframe, monitoring, within the first subframe, the common search space for the first NPDCCH without performing specific processing; and in a case that a common search space for a second NPDCCH scrambled by an RNTI corresponding to a Single-Cell Multicast Traffic Channel (SC-MTCH) is assigned within a second subframe, receiving, within the second subframe, an SC-MCCH transmission without monitoring the common search space for the second NPDCCH, wherein the specific subframe is (a) a first specific subframe within which an SC-MTCH transmission is assigned or (b) a second specific subframe within which the common search space for the second NPDCCH is assigned, the specific processing not performed within the first specific subframe comprising receiving the SC-MTCH transmission, the specific processing not performed within the second specific subframe comprising monitoring the common search space for the second NPDCCH.

2. A user equipment (UE), comprising: a processor; and a memory, wherein the memory stores instructions that cause the processor to: in a case that (a) a common search space for a first narrowband physical downlink control channel (NPDCCH) scrambled by a Radio Network Temporary Identity (RNTI) corresponding to an Single-Cell Multicast Control Channel (SC-MCCH) is assigned within a first subframe which is configured by a system information block and (b) the first subframe is a specific subframe, monitor, within the first subframe, the common search space for the first NPDCCH without performing specific processing; and in a case that a common search space for a second NPDCCH scrambled by an RNTI corresponding to a Single-Cell Multicast Traffic Channel (SC-MTCH) is assigned within a second subframe, receive, within the second subframe, an SC-MCCH transmission without monitoring the common search space for the second NPDCCH, wherein the specific subframe is (a) a first specific subframe within which an SC-MTCH transmission is assigned or (b) a second specific subframe within which the common search space for the second NPDCCH is assigned, the specific processing not performed within the first specific subframe comprising receiving the SC-MTCH transmission, the specific processing not performed within the second specific subframe comprising monitoring the common search space for the second NPDCCH.
